The document discusses the Pythagorean theorem, which was developed by Pythagoras in ancient Greece. It states that for any right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. The document then provides examples of how to use the theorem to calculate distances, including how far a baseball catcher must throw to second base and how high a ladder must reach to access a second story window.
